• Earth's rotation and revolution around the Sun take about the same amount of time.

• The Moon's rotation and revolution around the Earth take about the same time.

• The Sun appears to move from east to west because Earth is rotating from east to west

Samantha wants to test how the mass of an object affects the time it takes for the object to sink in salt water. She hypothesizes that the heavier the object, the fast the object will sink. Samantha will test objects that are 50 grams, 100 grams, and 150 grams. Which of these should she do to get the BEST data?

• use objects with different volumes.

• Use water from the same water source

• use the same tank of water for each object

• use a different stopwatch to time the sinking of each object

Which statement is NOT and example of scientific evidence about the properties of water?

• water can be a liquid, solid, or gas

• Cold water tastes better than warm water.

• Water boils at a temperature of 100 degrees celcius

Nickel is a magnetic metal. However, when a student holds a magnet to a nickel, the coin is not attracted to the magnet.

What is the MOST likely explanation for this observation?

• over time, the nickel has lots its magnetism

• there is plastic inside the coin

• there is another metal inside the coin that is not magnetic

• the magnetic field of a simple magnet is too weak to attract the nickel
